A New P-Value Based Multiple Testing Procedure with Arbitrary Dependence for Generalized Linear Models.


This study introduces a novel p-value-based multiple testing approach tailored for generalized linear models (GLM). Despite the crucial role of GLM in statistics, existing methodologies face obstacles arising from the heterogeneous variance of response variables and complex dependencies among estimated parameters. Our aim is to address the challenge of controlling the false discovery rate (FDR) amidst arbitrarily dependent test statistics. Through the development of efficient computational algorithms, we present a versatile statistical framework for multiple testing. The proposed framework accommodates a range of tools developed for constructing a new model matrix in regression-type analysis, including random row permutations and Model-X knockoffs. We devise efficient computing techniques to solve the encountered non-trivial quadratic matrix equations, enabling the construction of paired p-values suitable for the two-step multiple testing procedure proposed by Sarkar and Tang (2022). Theoretical analysis affirms the properties of our approach, demonstrating its capability to control the FDR at a given level. Empirical evaluations further substantiate its promising performance across diverse simulation settings.
